A little-known Ukrainian indie rock collective has captured the hearts of YouTube users—and Apple fans—with a cleverly shot music video that now has over half a million views.

Brunettes Shoot Blondes, an indie-rock band from Kryvyi Rih, an industrial town in Central-Eastern Ukraine, decided to take an unconventional approach to shooting their music video for the track “Knock Knock.” The 2.5-minute video tells its story using the screens of 14 different Apple devices: smartphones, tablets and laptops. The story's characters jump between screens as if by magic, moving from one device to another.

The video must have taken a lot of preparation, since the authors say it was shot in real time, in one take, using only one camera, and did not involve any post-editing. The result is an endearing love story set to an equally romantic soundtrack. What it conceals, most likely, is hours of design and animation work, as well as careful choreographing of the gadgets on the table. And, well, perfect timing.

As users continue to share the Ukrainian band's video masterpiece on the Web, some are jokingly speculating the video might secretly be an Apple promotion, since the devices play such a prominent part. We wonder if Apple might take note: the song—and the video—would make a for great Apple advert.
